what is the best apple watch for people with atrial fibrilation?
Question marked as
See the 'Irregular rhythm notifications' section in:
Heart health notifications on your Apple Watch - Apple Support
Be aware that the irregular rhythm notification feature on Apple Watch is not constantly looking for AFib. This means it cannot detect all instances of AFib, and people with AFib may not get a notification.
All versions of series 4 and newer watches should essentially work the same way.
